Hi

This is the final patch set in this slightly long HDR journey.

THe HDR algorithm here doesn't combine images to create HDR images
(there's no hardware for that), but it does allow the AGC to be driven
in such a way as to produce, for example, long and short exposure
images.

The second commit updates all the Raspeberry Pi camera tuning files. A
fairly simple change is made identically to all of them.

Thanks!
David
